In my first year of university, sitting in the classroom, a voice asked me every day:
"Why are you here?"

It wasn't a lack of effort. I studied hard, joined clubs, maintained good grades. But there was an empty space in my heart that wouldn't fill.

That year, I made a decision that surprised everyone—I dropped out.

No plan, no backup—only an intuition I couldn't quite explain: This wasn't the path meant for me.

After taking a leave of absence, I met someone who seemed to understand me.

That relationship taught me one thing: When you don't know yourself, you're easily defined by someone else's narrative.

PUA (emotional manipulation) isn't just something in movies. It happens in everyday life, in ordinary conversations.

It took me over two years to get out of it.

While getting out of it, I started reading obsessively— Psychology, self-awareness, personal growth... Like searching in books for an "aha!" moment.

I've tried dozens of tools—Notion, Obsidian, Roam, Logseq…… Each one made sense, but something was always missing.

Until I opened Heptabase.

That whiteboard interface made me feel for the first time: "My thoughts finally have a home."

I started reorganizing years of reading notes into it. One card, one link, one whiteboard……

Three months later, I had a knowledge map of my own— Over 1,000 cards, each one alive.

Then, people around me started asking: "How did you do this?"
